Quizplus · Accepted Answer

When an electron is moved from a low energy level to a higher energy level within an atom, the atom becomes excited. This is because the electron has gained energy and moved to a higher energy level. The atom is not ionized (option B) because it still has the same number of protons and electrons. The atom is also not dissociated (option C), which occurs when a molecule splits into separate atoms or ions. The atom is not in the ground state (option A) because it has gained energy. It is also not neutralized (option E) because it still has the same number of protons and electrons. When an electron is moved from a low energy level to a higher energy level, it absorbs energy and becomes excited. Therefore, the atom is now referred to as an excited atom.
